Determination of the Optimal Planting Period in Persian Clover (Trifolium Resupinatum L.), in Plain Conditions
Keywords:
dry matter, planting epochs, soluble sugars, Trifolium resupinatumAbstract
Persian clover (Trifolium resupinatum L.) represents an annual forage legume cultivated for forage quality and for its importance as ameliorating plant within the forage crop rotation. The researches performed on the determination of the optimal planting period at the beginning of autumn proved the existence of a direct relationship between the sum of temperatures at planting, at the beginning of winter, and the dry matter yield, respectively between the number of sprigs at the beginning of winter and the content in soluble sugars in roots. According to planting date, the dry matter yield oscillated between 1.5 t/ha in the variant planted on 20th September and 9.4 t/ha in the variant planted on 10th August.
